Facility Relocation Models Utilizing Existing Facilities

摘要

The paper presents facility relocation models that provide with solutions for the problem whichfacilities to be closed and to be newly opened, with the constraint of the number of opening andclosing facilities. The objectives are the minimization of total travel distance from the patrons totheir closest facility, or the maximization of the number of patrons covered by the facilities withpredetermined radius from the facilities. The models can be applied for both of the cases: thetotal number of facilities is increasing and decreasing. They are useful for selecting facilities toclose and determining the location of facilities to open, when we face with financial exigency andare forced to utilize existing facilities. Through two case studies, we observed that only a fewrelocation of existing facility can improve current status and realize nearly optimal status intravel distance or demand covering.
